This PulseDrive pulse program is set up for Union NiMoCr wire, 1.2 mm diameter, with M20 shielding gas. Pulsed arc and double pulse make thin sheet and positional welds easier.
What it is for
The program holds synergic curves for this one combination of wire, diameter and gas. You change wire feed speed or plate thickness and the machine sets voltage and arc shape itself. The program is meant for high-strength steels, where repeatable heat input and a stable arc matter. The 1.2 mm diameter suits medium and thicker plate, typical in fabrication work.

FAQ
Which machine can run this program?
Any machine on the list above. TERRA NX 320/400 SMC SteelDrive and TERRA NX 400/500 MSE are not listed for PulseDrive in the selection guide. When ordering, give the model and serial number of the machine the program is for. Installation, by our service or as a manufacturer update, is agreed after the order.
PulseDrive or QuickPulse?
QuickPulse is a T.MAP process: the price list credits it with faster welding, higher deposition rate, a more concentrated arc and less heat. It covers fewer machines, not URANOS NX 2700. QuickPulse for this set-up: QuickPulse 1.2 mm, gas M20 (79.QP.21399).
Can I use another ER100S-G wire?
The curves are tuned to Union NiMoCr. Another wire may behave differently, so contact us and we will match a program to the wire you use.
